Patent US-1866-53582

- Tech class CPC F42B15/01: Arrangements thereon for guidance or control
- Interesting case of citing patent filed 1944 and published 1947; that seems to mark the earliest known citing patent that google patents picks up; matching claim in Hammarfelt paper that 1947 is when patent examiner citations start to show up in the data.
- Inventor location: Philadelphia, Philadelphia county, PA (FIPSloc=42101, imputed by HistPat)
- From diagrams page we infer that the name is De Coursey not de Coursey, and although it's written as DeCoursey with no space on the diagram page, it can't be like that or it would be shown that way in the three other places the name appears in the patent doc.
